Corrugated sheets are made of heavy plastic or PVC. Both types of corrugated sheets can be used as roofing or siding in basic construction. Corrugated sheets have some advantages over traditional roofing and siding material because they are inexpensive and easy to work with. Cutting corrugated sheets is not that difficult if you learn to manage the uneven surface of the sheet. This takes a bit of practice and a few basic steps.
Measure your sheet and use an oil pencil to mark the section that will be cut.
Lay the corrugated sheet on a hard, flat surface and cut on the lines you marked with the oil pencil, using a fine-toothed hand saw or circular power saw. Adjust your saw depth while moving the corrugated sheet so that it rises and falls along with the corrugation to prevent the sheet from cracking.
Sand away rough edges, splinters and sharp spots with a piece of fine sandpaper. Use a gentle side-to-side motion to sand against the cut edge of the corrugated sheet.
Purchase an extra sheet and practice cutting it a few times before attempting a project.
Use safety glasses and heavy gloves to protect against injury.
